Colin carries on with his analysis of boat heating systems covering propane heaters and diesel furnaces, both forced air, and water circulation as well as radiators that harvest waste heat from the engine.
You don’t need to be heading for the high latitudes to appreciate the benefits of a boat heater. Just drying the boat out can be reason enough to make installing a heater worthwhile. But which type is best? Colin shines a light on the options.
[While living on Polaris for a month, I wrote about the boat’s kerosene stove (cooker), which sparked a lively debate in the comments about the benefits and drawbacks of various cooking fuels on boats. Continuing that theme, we just got a note from our good friend and Norwegian Correspondent for the Norwegian Cruising Guide, Hans [...]
Question: Could you post detailed photos to your website of the wooden bezels you fitted to your ports to accept Plexiglas covers? Did you do the same for your hatches? We are losing the battle against condensation in Florida’s current cold snap. Thanks! Answer: When we were battling condensation during our two winters in arctic [...]
We have long heard the praises of the Danish Refleks diesel drip heater sung by the many expedition sailboat owners that have them, but since we simply don’t have a good place for one, or its chimney, on Morgan’s Cloud, we had never had the chance to use one before the month we spent on [...]
Question: Could you please address the fuel consumption of forced-air bus heaters vs. the Refleks? Answer: An accurate comparison of fuel consumption and relative efficiency between the two technologies would require equipment and time we don’t really have at our disposal. However, since both systems burn with an essentially clear exhaust, indicating good efficiency, and [...]
Question: My experience with diesel heat is that it’s hard to light, hard to control, it smells and the deck is covered in soot. That was 25 years ago with the stainless steel pot belly stove in [a] Westsail. You rave about the Espar diesel heater. Is the Espar really that good and does it [...]
Question: What do you use for heating on Morgan’s Cloud? Answer: We have an Espar D8 8KW (I’m not sure of the BTUs). It is one of the bigger ones they make and keeps us toasty in all weathers. One thing I would suggest is not to use the exhaust exit in the hull that [...]
Question: Is keeping the interior of the boat dry in the midst of prolonged damp, chilly weather, and/or sea spray just a matter of dorade vents, hull insulation and your Espar heater? Do you have success keeping the interior dry or does it inevitably get damp? Answer: If you already have a boat, there are [...]
After years of fighting with an unreliable diesel heater, we are very pleased with the Espar heater we installed in 2000. It is one of the bigger ones they make and keeps us toasty in all weather. One thing we would suggest, though, is not to use the exhaust exit in the hull that they [...]
